The lake is a reservoir that arose naturally, filled with water within fairly strict limits and at the same time does not have a connection with the sea or ocean. In total, there are about five million lakes in the world. The living conditions in them differ from sea, for example, in most cases lake water fresh.
Pisces here are appropriate, lake. They are also called river, since similar species are often found in fresh rivers. One of the main differences can be called small sizes, a developed skeleton and the absence of a large number of bright colors. Consider the most typical representatives of the lake fish.
Other fish of lakes
Many lake fish look “classically” and are similar to each other. They are “distinguished” by a similar color, location and shape of fins, the nature of movement in water. Among them there are species that stand out among the rest. This, first of all, includes the subcamper, the Igla fish, Malma, Kumzha, Rotan and Siberian concealment.
Life in the lake imposes various features on the behavior and capabilities of fish. For example, a rotan is able to live in very small reservoirs, which freeze to the bottom in winter. At the same time, he does not die, but gets down into the pack and freezes into the ice. In the spring, when the lake thaws, Rotan leaves the “hibernation” and continues the usual existence.
Unlike marine “brothers”, the lakes do not make long nomads for spawning. Although individual species are able to enter the channels of flowing rivers. The main lover of swimming against the current is trout.
A very large number of lake fish are an object of fishing. Industrial catch on lakes, as a rule, is prohibited due to small livestock. But the fish is actively caught for fishing and other devices single fishermen. In some areas of the globe, fish from the lake and similar water bodies are the basis for the nutrition of local residents.
